Title: Catalyst for hydrocarbon contact combustion and method for particulate matter removal from exhaust gas
Inventor: TANAKA SATOSHI
IPC: B01D53/94
Filed: 2000-10-31
Abstract: PROBLEM TO BE SOLVED: To produce a catalyst for efficiently carrying out contact combustion of a trace of hydrocarbons in an exhaust gas even at a relatively low temperature and provide a particulate matter(PM) removal method using a catalyst layer-filter system and applicable for an exhaust gas from any type of fuel. SOLUTION: A first catalyst comprises platinum and tellurium deposited on a refractory inorganic compound. A second catalyst comprises the first catalyst further containing selected elements such as boron and satisfies the following inequality: 0.005<=(total weight of selected elements)/(Pt weight)<0.25. The PM removal method is carried out by introducing an exhaust gas together with hydrocarbons into a catalyst layer for hydrocarbon contact combustion to burn the hydrocarbons, introducing the obtained high temperature exhaust gas into a filter to collect PM in the exhaust gas, and burning the PM at a high temperature to regenerate the filter. The catalyst layer is preferabl to be filled with the hydrocarbon combustion catalyst of this invention further having activity to remove nitrogen oxides.
